Application filed novmber 9, 1907. Serial No. 401,517.

To all whom it may concern residing at Larchmont, in the county. of Westchester and State of New York, have invented certain new and useful Improvements in Insectifuge, of which the following is a specification.

This invention relates to a composition for repelling moths and preventing their destructive action on textile material, etc., and relates particularly to absorbent granular material impregnated with active organic bodies.

The use of granular absorbent material 'per-' mits ofthe cheap' application of otherwise expensive active or ranic agents in a form which makes them non-injurious to textile material.

An illustrative formula comprises 20 parts of carnauba wax and 10 parts of ceresin wax, which are melted and mixed-- with '5 parts of oil of cedar wood, 3' parts of oil of cedar leaf, 2' parts of heavy oil of camphor and 5 parts of methyl salicylate. This. oil

and wax'mixture is cooled and when thor oughly solid is pulverized. Seven parts, by weight, of this mixture are then mixed with six parts, by.weight,.of sawdust which has passed a 20-mesh sieve. 'This mixture is heated to 'a temperature sufficient to melt the waxy composition, thereby causing impregnation of the sawdust material.

Another illustrative formula comprises" naphthalene 30 parts, oil oflcedar leaf 10 parts and sawdust 60 partss The oil of cedar leaf-is melted with naphthalene, and.

the mixture .then cooled and pulverized. Sawdust should be preferably employed whichhas passed a20- mesh sieve." Ordinary pine sawdust is sufficient for the purpose. The retentive properties of the sawdust are increased by charring slightly and .for this Be it known that LjCARLETomELLIs, a citizen of the United States,

purpose it may be heated with'agitation in a suitable receptacle such as a rotating drum or cylinder until it has become slightly disoil mixture is "intimately mixed with the sawdust and the mass heated until the sawdust has substantially absorbed the naphtha lene and oil.

Other active agents may be similarly employed, those specified 'above being especially eflicient for this purpose. I Cedar wood sawv dust may be used. I Having described my invention, to the details of which I of course do not limit myself, what I claim is: a

1. An insectifuge comprising granular absorbent material, including sawdust carrying insectifugal material of an oily character pregnated with oil of cedar leaf, and naph tha-lene. p

8. An insectifuge comprising charred sawdust impregnated with naphthalene and oil of cedar leaf, substantially as described.

4. An insectifu e comprising absorbent organic material, including sawdust in a slightly charred condition, impregnated with essential oil material: including oil of" cedar g 75 leaf, and naphthalene.

In testimony whereof I have aflixed my signature inpresence of two witnesses.
